I setup a GitLab Page that uses a custom domain and it serves up an Angular application. If I go to mywebsite.com it works and I can navigate around the app no problem.
If I attempt to access the page via mywebsite.com/about (a valid path), for example, it 404's. The routes are handled correctly in the Angular app and should work since I've used this same routing code in other projects with no problems.
Any idea how to fix this?
Turns out this is because it's an Angular app and since they only generate one index.html, any attempt to resolve other paths fail since about.html doesn't exist.
